    Default Used Vermiculite?

    I've not really worked out which potting compost to buy over here yet for sowwing seeds. (It seems to be either very fibrous or peaty- French Grapes please suggest what you find works best!!!)

    And so- we've used vermiculite mixed in and had much better results
    BUT

    Normally I chuck spent potting compost onto the beds but vermiculite seems to stay in the soil.
    I can see that in years to come it'll build up in the top soil.
    So....what do other peeps do who use vermiculite? My soil is already sandy so I don't need the extra drainage it provides.

    Vermic also holds moisture so if your soil is sandy, the vermic will be very useful indeed

    Oh good - daft ol' me thought it was just to lighten the potting compost to allow better drainage!

    I understand (from somewhere) that because of the huge surface area of vermiculite due to it being porous that it will not only hold on to water on its surface but also soluble nutrients in that water.
    Only from what I have read and can remember you understand.

    A relatively old post now, but thought I'd share anyway.

    Vermiculite does retain both moisture and nutrients (to a certain extent). It's useful as it will hold a quantity of water (so good for retaining moisture) but also once that capacity is reached it is useful for drainage.

    For the record the cheapest place to buy vermiculite is at a building suppliers (Jewsons). It's about 16 a 100L bag (although I have a discount code for 10 :P ) and it's much, much cheaper than a garden centre (about 10 for 10L).
